The SpectraDrive high-quality bass preamp is ported directly from TC Electronics line of bass amps, and gives you exceptional tonal options for practice, live and studio performance. TubeDrive with TonePrint technology emulates preamplifier and power amplifier tube stages, offering you everything from subtle drive to full-on distortion. And the SpectraComp control with TonePrint technology provides a variety of ultra-transparent and highly musical multi-band compression profiles to cut through any mix. That's coupled with an intelligent EQ stack dedicated to bass with four simple control dials to give you easy and impressive tone-shaping. The balanced DI with pre/post switch allows direct connection to mixing consoles or recording equipment. Superior analog buffering from the Bonafide Buffer pedal prevents signal distortion from long cable runs. And for added versatility, it offers parallel outputs for tuning or sending clean signal to your amp and mixer. The SpectraDrive also features an auxiliary rehearsal input for playback through speaker or headphones. And the studio-quality headphone amplifier with speaker emulation delivers for personal practice and silent rehearsals.
